Kev txheeb xyuas qhov teeb meem zoo thiab kev tiv thaiv ib puag ncig ntawm cov khoom txaj hauv kuv lub tebchaws

Author: Synwin– Kev cai txaj txaj

Lub txaj yog ib qho tseem ceeb ntawm cov khoom siv ruaj khov hauv tsev, thiab nws qhov zoo cuam tshuam ncaj qha rau tib neeg kev noj qab haus huv. Muaj peb yam tseem ceeb ntawm cov khoom txaj hauv kuv lub teb chaws: lub caij nplooj ntoos hlav mos txaj txaj, xim av fiber ntau elastic txaj, thiab ua npuas ncauj txaj. Lub caij nplooj ntoos hlav mos lub txaj hais txog cov txaj txaj uas ua los ntawm lub caij nplooj ntoos hlav thiab cov ntaub mos muag raws li cov khoom siv hauv cov tub ntxhais, thiab qhov saum npoo yog npog nrog lwm cov ntaub ntawv xws li ntaub ntaub lossis lub rooj zaum muag muag.

Brown fiber ntau elastic txaj yog hais txog cov khoom siv elastic nrog cov qauv ntxeem tau tsim los ntawm kev siv cov xim av fiber ntau ua cov khoom tseem ceeb, thiab siv cov nplaum ua kom lawv ua raws li kev sib txuas los yog siv lwm txoj kev sib txuas. Foamed txaj yog hais txog lub txaj ua los ntawm ntuj latex, hluavtaws latex, polyurethane thiab lwm yam ntaub ntawv, uas yog tsim los ntawm foaming txheej txheem raws li cov khoom tseem ceeb, thiab saum npoo yog them nrog fabrics thiab lwm yam ntaub ntawv. 1 Cov Qauv Khoom thiab Cov Qauv Tseem Ceeb Cov qauv khoom thiab cov qauv tseem ceeb thiab kev tiv thaiv ib puag ncig ntawm cov khoom siv hauv txaj yog raws li hauv qab no: QB/T 1952.2-2011 "Spring Soft Mattress for Upholstered Furniture"; GB/T 26706-2011 "Brown Fiber Elastic Bed for Upholstered Furniture" Mats"; QB/T 4839-2015 "Foam Mattresses for Upholstered Furniture"; GB 18587-2001 "Limits of Harmful Substances" Released Carpets, Carpets thiab Carpet Adhesives"; GB 17927.1-2011 "Upholstered Furniture beds" Kev ntsuam xyuas ntawm qhov hluav taws kub tsis kam ntawm cushions thiab sofas - Ntu 1: Smoldering luam yeeb"; GB 17927.2-2011 "Kev ntsuam xyuas ntawm qhov hluav taws kub tsis kam ntawm cov rooj tog zaum, txaj thiab sofas - Ntu 1: Simulated match nplaim"; QB/T 1952.2— 2011 "Spring Soft Mattress for Soft Furniture" feem ntau qhia txog qhov sib txawv ntawm qhov loj me, cov tsos ntawm cov ntaub, seam zoo, lub cev lub cev ntawm cov ntaub thiab cov ntaub pua chaw pw, kev nyiam huv thiab kev nyab xeeb, kev tiv thaiv kab mob, lub caij nplooj ntoos hlav zoo thiab cov khoom siv thiab lub cev ntawm lub caij nplooj ntoos hlav mos txaj tos.

GB / T 26706-2011 "Soft Furniture - Brown Fiber Elastic Mattress" feem ntau hais txog qhov sib txawv ntawm qhov loj me, cov tsos thiab kev ua haujlwm, cov khoom siv tseem ceeb thiab kev ua tau zoo, kev nyab xeeb thiab kev noj qab haus huv yuav tsum tau ua, nplaim taws ua haujlwm zoo thiab ua haujlwm ntev ntawm cov ntaub pua rooj. QB / T 4839-2015 "Foam Mattress for Upholstered Furniture" feem ntau qhia txog qhov sib txawv ntawm qhov loj me, qhov tsos ntawm cov ntaub, seam zoo ntawm seam nto, lub cev khoom ntawm cov ntaub thiab cov khoom siv tseem ceeb, nplaim hluav taws thiab tiv thaiv mite kev ua haujlwm ntawm lub txaj txaj. , formaldehyde emission, diisocyanate monomer thiab txhua yam thiab lub cev muaj zog. 2 Cov teeb meem zoo thiab kev tiv thaiv ib puag ncig) muaj kev xav, cov txiv maj phaub mats thiab lwm yam ntaub ntawv.

Cov ntaub ntawv tseem ceeb ntawm cov xibtes fiber ntau elastic txaj feem ntau suav nrog roob xibtes fiber ntau lev, txiv maj phaub fiber lev thiab roj xibtes fiber lev. Nyob rau hauv xyoo tas los no, ib hom tshiab ntawm ib puag ncig tus phooj ywg cov khoom tseem ceeb, feem ntau hu ua ib puag ncig tus phooj ywg xim av, tau tshwm sim ntawm kev ua lag luam. Lub hardness ntawm cov khoom no kuj yog siab, uas ua tau raws li cov kev xav tau ntawm qee cov neeg siv khoom uas nyiam pw ntawm lub txaj tawv.

Cov khoom siv tseem ceeb ntawm cov ntaub pua tsev ua npuas ncauj feem ntau suav nrog cov yas ua npuas dej, cov roj hmab ntuj, hluavtaws latex thiab lwm yam ntaub ntawv tsim los ntawm cov txheej txheem foaming. Qhov teeb meem zoo thiab kev tiv thaiv ib puag ncig ntawm cov ntaub ntawv txaj yog tsom rau cov khoom siv ua npuas ncauj thiab kev nyiam huv. Lub txaj saum npoo yuav raug crushed rau ib qho twg thaum siv, thiab qhov ua tau zoo ntawm cov npuas dej muaj feem xyuam nrog lub peev xwm ntawm lub txaj txaj kom rov zoo tom qab compressed.

Qhov ua npuas ncauj resilience tsis yog raws li tus qauv, uas yuav ua rau cov pits ntawm qhov chaw ntawm lub txaj thiab cuam tshuam rau kev nplij siab ntawm cov khoom. Cov kev cai tu cev ntawm cov ntaub pua tsev yog ib qho tseem ceeb zoo thiab kev tiv thaiv ib puag ncig hauv cov khoom txaj. Qhov zoo ntawm cov khoom siv hauv txaj siv hauv lub txaj yog cuam tshuam rau tus kheej kev noj qab haus huv thiab kev nyab xeeb thiab kev xav ntawm kev siv.

Qhov laj thawj tseem ceeb ntawm kev tsis ua raws li kev cai huv ntawm cov ntaub pua tsev txaj yog cov ntaub ntawv txaj yog tov nrog cov ntaub ntawv yas, cov straws lossis nplooj, plhaub, xyoob lo lo ntxhuav thiab ntoo shavings, thiab qee qhov siv cov khoom siv fiber ntau zoo sib xws. Cov ntaub ntawv yas yog feem ntau siv lub hnab ntim khoom, thiab qee lub hnab ntim khoom tseem muaj cov khoom siv tshuaj xws li tshuaj thiab chiv. Cov khoom siv fiber ntau pov tseg thiab cov ntaub ntawv yas woven no yooj yim heev los yug cov kab mob thiab cov khoom tsis zoo hauv kev siv mus ntev. , cuam tshuam rau tib neeg txoj kev noj qab haus huv. 2.2 Nplaim retardancy Nplaim retardancy yog lwm qhov tseem ceeb ntawm cov khoom siv txaj.

Cov ntaub ntawv raw siv hauv txaj yog feem ntau flammable fabrics, foam plastics, paj rwb ntaub ntaub, thiab lwm yam. Yog li ntawd, lub txaj yuav tsum muaj ib qho kev tiv thaiv rau ignition. kuv lub teb chaws tau muab cov nplaim hluav taws sib txawv rau cov khoom siv hauv txaj rau tsev neeg thiab cov chaw pej xeem. Tsev neeg lub txaj yuav tsum dhau qhov kev sim tiv thaiv hluav taws kub ntawm cov luam yeeb, uas yog, cov khoom tiv thaiv hluav taws xob yuav tsum ua tau raws li cov cai ntawm GB 17927.1-2011; Cov chaw pej xeem cov txaj siv yuav tsum xeem dhau qhov kev sim tiv thaiv hluav taws xob simulating nplaim taws, uas yog, cov yam ntxwv tiv thaiv hluav taws xob yuav tsum ua tau raws li cov cai ntawm GB 17927.2-2011. Vim tias cov ntaub pua plag siv hauv cov chaw pej xeem feem ntau siv rau hauv cov chaw uas muaj neeg coob coob thiab cov vaj tse nyuaj, thaum hluav taws tshwm sim, nws yuav ua rau muaj kev puas tsuaj loj rau tus kheej thiab cov khoom ntiag tug, yog li cov kev xav tau ntawm cov nplaim hluav taws kub hnyiab tau kuj siab.

Rau cov khoom txaj kom dhau qhov yuav tsum tau ua, cov ntaub pua tsev yuav tsum yog nplaim hluav taws, lossis cov ntaub thiab ntaub pua chaw yuav tsum yog nplaim taws. 2.3 Formaldehyde emission Formaldehyde yog ib yam tshuaj lom neeg thiab muaj teeb meem. Kev siv lub txaj ntev ntev nrog formaldehyde emission ntau dhau yuav ua rau muaj kev phom sij ntau dua rau tib neeg lub cev. Raws li lub txaj rau cov neeg pw tsaug zog ntev, kev tswj cov formaldehyde emission los ntawm lub txaj yog qhov tseem ceeb tshwj xeeb.

Lub formaldehyde ntawm lub caij nplooj ntoos hlav mos txaj yog los ntawm cov ntaub ntawv textile, cov ntaub qhwv xim av, thiab lwm yam. siv. Muaj ob lub laj thawj tseem ceeb rau kev tso tawm ntau dhau ntawm formaldehyde los ntawm lub txaj: (1) Lub txaj textile ntaub muaj formaldehyde. Nyob rau hauv cov txheej txheem ntawm fabrics, dyes, anti-wrinkle agents, preservatives thiab lwm yam auxiliaries yog siv rau xov. Yog tias cov auxiliaries muaj formaldehyde, nws yuav ua rau cov formaldehyde tshaj tus qauv; (2) Cov tshuaj fiber ntau, cov txiv maj phaub xibtes lossis cov khoom siv ntuj xws li roob xibtes thiab cov yas foamed tsis muaj formaldehyde, tab sis txhawm rau ua kom lub zog thiab tawv tawv ntawm cov ntaub ntawv, qee lub tuam txhab siv ntau cov formaldehyde-muaj cov nplaum nplaum hauv cov txheej txheem tsim khoom, ua rau muaj formaldehyde loj tshaj tus qauv. Txawm hais tias twb muaj formaldehyde-dawb nplaum nplaum, cov nqi feem ntau yog siab, thiab feem ntau cov khoom siv raw yuav tsis siv lawv.
